Look carefully at all the permissions on the file system that fails and compare them to the filesystems that are working. Somewhere there is a difference between the working filesystems and the failing one, and you are going to have to track it down. It is almost impossible to guess what it would be without being there. <div class="Ih2E3d">-- Bob Sloane, University of Kansas Computer Center, Lawrence, KS, 66045 <a href="mailto:Email:sloane@ku.edu"> Email:sloane@ku.edu</a> <a href="http://www.ku.edu/home/sloane" target="_blank">http://www.ku.edu/home/sloane</a> Phone:(785)864-0444 -----Original Message----- From: <a href="mailto:nagios-users-bounces@lists.sourceforge.net"> nagios-users-bounces@lists.sourceforge.net</a> [mailto:<a href="mailto:nagios-users-bounces@lists.sourceforge.net">nagios-users-bounces@lists.sourceforge.net</a>] On Behalf Of Jake Solid </div><div><div></div><div class="Wj3C7c"> Sent: Friday, January 11, 2008 10:35 AM To: <a href="mailto:nagios-users@lists.sourceforge.net">nagios-users@lists.sourceforge.net</a> Subject: Re: [Nagios-users] DISK UNKNOWN - free space Sorry.

From one of your previous posts: *The one I was having issues with is:* command[check_disk4]=/usr/lib64/nagios/plugins/check_disk -w 20% -c 10% -p /dev/mapper/VolGroup01-fredVol00 * Which is mounted on* /dev/mapper/VolGroup01-fredVol00 119G 107G 5.8G 95% /vservers/fred/data That is a pretty big volume (well, big to me since I grew up with 540M being HUGE). I have a similar problem using "check_disk" to verify the free space on a 16 Terabyte volume (on Solaris 10). Please humor me and read the post that I made to this group on 2008-1-7 at 4:28pm (CST). I don't remember what OS you are using... But please run the "check_disk" program through the syscall logger for your OS. On Linux: strace /usr/lib64/nagios/plugins/check_disk -w 20% -c 10% -p /dev/mapper/VolGroup01-fredVol00 On Solaris: truss /usr/lib64/nagios/plugins/check_disk -w 20% -c 10% -p /dev/mapper/VolGroup01-fredVol00 On FreeBSD (from memory, I could be wrong): ktrace /usr/lib64/nagios/plugins/check_disk -w 20% -c 10% -p /dev/mapper/VolGroup01-fredVol00 Near the bottom you should see a call to "statvfs" or something similar (again, read my post first). Do you have the same error that I do? In my case, the nagios-plugins package was compiled without support for "fs64", so it used the older "statvfs" which can't handle huge disk volumes. The kernel call returned an error instead of the volume info. -- CONFIDENTIALITY NOTICE This electronic mail and the information contained herein are intended for the named recipient only.
